Ohio State University researchers are working with startup Nikola Labs to commercialize the technology

Cell phones are constantly transmitting radio signals, whose energy can also be used to boost the battery life of mobile devices.

Researchers at Ohio State University have developed circuitry that converts radio signals from a handset into energy, which is then fed back to the device’s battery. The researchers say the technology can increase the battery life of mobile devices by up to 30 percent.

The OSU researchers are working with startup Nikola Labs to commercialize the technology, which they say can be easily implemented in cell-phone cases, and in June will launch a Kickstarter campaign to fund its continued development.

Nikola Labs pitched the concept of an energy-harvesting iPhone 6 case based on the technology at the TechCrunch Disrupt conference earlier this month. Nikola Labs estimates the case will be priced at $99.
